To all 1y/ wm it may concern:

Be 1t known that we,"`WILLIAM, KLoonn end ,loiiiv E.. Do BsoN, citizens of tlieUnited States oi' America, `residing, respectively, in

the borough of Queens and borough of Manhatt-an', city and Stateof. `New' York, have invented Acertain new anduiseful Improvements. inMechanical Movements,` of which the `following is a specification.

This invention.. .relates to mechanical movements, ,and aims to provide improvements therein.

The invention provides a. me chanism or. so-called mechanical movement by means ot which a part may be given Ia reciprocatory movement'vvitha gentleretardatio-n and acceleration at `the extremes of its movement, and at the same time dwells of considerable duration given to the reciprocatorypart at said extremes', the dwell; at `one extreme be- ,ing capable of-fbeing' .prolonged Vbeyond the dwell at the other extreme.

' The invention further provides a mechanism or movement comprising a rocking part, ,atoggle, and'a link, and which, may be actuated by a rotary part, wherein thecharacter of reciprocation referred to above may be carried out, and wherein the dwell of longer duration referred to above, may have'.

a4 length corresponding to 12W- 140j of movement oit' a crank or similar driving v, part.

#The invention -further provides a mechal n comprisesr a rocking part or shaft 17, a part nism or Ji'novementi Awherein anV angular movement of 180'may be imparted to aroclrling part by a part having Va short angular movement and a toggle connecting saidlatter part to said rocking part.

""ghe. invention further provides a novel combination of parts for effecting a movet ment of the character referred'to above.

An embodiment ofi-the invention .applied as an operating means Jfor the feed slide of am press, is'illustrated in .theaccompanying drawings, of whichvembodimentr- Figure. lis a view inside elevation.

the connection 'between' the slideig. .lshows'the parts in the position which they occupy when in the opposite extreme position to that shown in Fig. 1. Fig. 5 is a view in section on the line 5-5 F ig. f1, looking in thedii'ectioii of the arrows. Referring to said drawings, numeral 1 designates .a reciprocatory-part to be actuated, as .or example the feed'slide` of a press. Numeral 3 designates a plungenadapted to .carry a punch or the like and conveniently actuated by a rot-arvciank shaft 6, driven 1n any suitable manner, as by means of a fly-wheel pulley 8, the4 'plunger 3 andcrank shaft 6 being conveniently connected by a connecting` rod 9.

13, designates adie, and 14 a-tablefsubstantially flush with the top of the die, and along which a blank is'adapted to beslid bythe said slide to a position over -said die, in line withthe punch'. 1 VThe slide is suitably theformliere shown is `provided@with an ,elongatedopening 2, equaling in length the throw ofthe slide plus the diameter of the blank.

15- designates-the- -means or movement for imparting to the-saidl slide 1, a reciprocatory movement of the character referred to, that is, one with a 'gentle Yretardation and acceleration at the `extremes of its movenient, and with dwells orf-considerable-duration at said eXtremes."`The mechanism 15 19 having a short angular or--equivalent movement,A as foneXa-mple a guidelink or lever turning around anaXis' 20, ora guide moving similarly to' the end of said lever anda toggle 22-connectingsaid rocking part 17 and thepart 19 havingthe Vshort angular movement, the toggle 22 being yconstituted by an arm 2e onsaidrocking 4part 17,- and a link 26 -connected at the lineeV 23 to said-arm 24 and to the part or lever 19.

The part 19 witlithe short angular movenientv is;reciprocatedl -through its -1 arc of c movement by anyysuitable -means,=`conven liently, `arctary part,`- which may be a-disc 28- on thefcijankysliaft 6lifaving thereon a cranlrpi-n 30. trod oir-link32 serves to con- Vneet the-crank; pin`.30 and-one ofv thev con- 'position where the slide 1 nected parts 19, 26, conveniently the part 19. The part 19 may be provided for this purpose with a pin 34.

The rocking part 17 may be connected to the slide 1 by any suitable means, conveniently, as here shown, a toggle 40, consti tuted by an arm 11 on said rocking part 17 and a link 42 connect-ing said arm and slide, Fig. 3.

The arrangement ot the parte of the movement is such that the joined ends of the part or lever 19, and the link 26, at one extreme ot movement, move in substantially Y parallel arcs around their pivots 20 and 23 respectively; and at the same time the arrangement is preferably such that the link /12 and arm l1 ot the toggle '-10 are substantially in line; and at the same time the arrangement is further preferably such that the crank pin 30 is passing over its dead center; the combined e'li'ect ot which is to provide a prolonged dwell of the slidel in one oic its entren'ie positions. as forl example that has moved the blank in line with the punch 4 (Fig. 1l.

Operation: lith the parts in a position shown in Fig. l a blank may be laid on the table 14 through the opening 2 in the slide, out ot line with the punch. Movement ot the part or lever 19 downward. will canse the parts 21.V 26 of the toggle 22 to move together or close, thereby turning the rooking part 17 in a clock-wise direction` the rock shaft 17 starting from a condition ot rest, and gradually accelerating as the parts 24,26 of the toggle 22 close together, the

, turningof the rocking part 17 being quite rapid when the part or lever 19 has reached about one halt ot its are ot movement., position a, Figs. 1 and el. The' turning of the rocking part 17 will be gradually retarded as the part or lever 19 moves past its mid position (position a) toward its extreme position shown in Fig. 1. fis the part or lever 19 moves 'trom the vicinity oi a point b in its movement to its extreme position shown in Fig. 1, there will be substantially no turning movement ot the rock shaft 17, and consequently there will be a dwell oic the slide 1 and the blank ted thereby in. a position in alinement with the unch el, owing to the tact that the point 27 at the joint ot the part 19 to the link 26 is moving in an arc which is substantially parallel 'to an are described by said point 27 around the point 23 joining said link 26 with arm 211. rl`he dwell is made more pronounced by the employment ot the toggle 40 and by its arrangement such that its legs L11, 42, approximate alinement at this period. The employment of the crank 30 and its arrangement such that it is mov ing across its dead center (at 2700) with respect to the rod 32, also contributes to the perfection ot the dwell.

On the reverse movement or" the part 19, i

rapid at about the point a in the movement Y of said part 179.- At this time the slide 1 will be approachingthe/position shown in Fig. 4l, the movement ot saidslide `1 being gently retarded as the position otv Fig. l is reached, owing to the legs 24-26 ot' the toggle 22 straightening, and the simultaneous straightening of the legs 41-12 of the toggle l() and the movement of the crank' 30 towards its dead center position (at 90). f i

The arrangement is preferably such that the punch l acts on the blank while the slide 1 dwells in the extreme position. of Fig. 1 and the ejection of the drawn article may take place through the opening 2 inthe side, ywithout regard to the position of the s ic e.

ln the position of Fig. 4 there is a dwell owing to the relatively straight position of the legs 24l26 ot' the toggle 22, and the reversal of movement of said part 19, accentuated, Vwhen the crank 30 and toggle L10 are employed, by the movement of said crank 30 across its dead center (at 90") and by the alinement of thelegs 11e-e2 of said toggle 410. The cycle described is'repeated at each reciprocation or oscillation of the part 19. By the arrangement described, the rock-shaft is given a Vmovementi-.through an angle of 18.0 as compared withan angle of about 60 described by the part 19 and the slide is given a. dwell in the extreme position of Fig. 1 corresponding to about 125o of movement oi' the crank pin 30.
